Title:
RECORDING MATERIAL COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/103161
Kind Code:
A1
Abstract:
The purpose of the present invention is, in a recording material cooling device configuration with upper and lower belts 51, 52 wherein heat sinks are disposed above and below, to efficiently use space within the belts forming a nip part for cooling recording material and to improve heat dissipation efficiency in a heat dissipating part in relation to a heat receiving part in contact with the inside peripheral surface of the belts. In the configuration with lower belts 51, 52 wherein heat sinks 53, 54 are disposed above and below, the heat absorbing parts 53a, 54a (belt contact parts) of the heat sinks are disposed so as to be offset in the direction of a paper path and not to come in contact with each other via the belts 51, 52; however, heat discharging parts 53c, 53d and 54c, 54d of each of the heat sinks 53, 54 are disposed so as to be expanded to overlap in the direction of the paper path with the heat absorbing part of the heat sink on the opposite side. Thus, heat dissipation efficiency can be improved in the limited space within the belt cross-section. Accordingly, it is possible to reduce the size of the recording material cooling device, and achieve faster operations.
